Description
ZINC SILICOFLUORIDE is a white crystalline solid material that is insoluble in water and denser than water. It may cause irritation to skin, eyes, and mucous membranes upon contact and is potentially toxic if ingested. This chemical compound decomposes upon heating and has a variety of applications across different industries.
Uses
Used in Construction Industry:
ZINC SILICOFLUORIDE is used as a fast hardener for concrete, enhancing its strength and durability. It is also employed as a wood preservative to protect against decay and insects, as well as a plaster enhancer to improve the quality and workability of the material.
Used in Pest Control:
ZINC SILICOFLUORIDE serves as a postscrubbing agent and a mothproofing agent, helping to protect fabrics and other materials from damage caused by insects.
Used in Textile Industry:
ZINC SILICOFLUORIDE is used as a catalyst in the production of polyester fibers, contributing to the efficiency and quality of the manufacturing process.
Used in Electrolytic Processes:
It is an essential ingredient in the electrolytic bath for preparing zinc, playing a crucial role in the electrochemical production of this metal.
Used in Surface Treatment:
As an additive for hardening and polishing concrete surfaces, such as floors or walls, ZINC SILICOFLUORIDE improves the durability and appearance of these structures.
Used in Cleaning Agents:
A pasty mixture prepared by combining zinc fluosilicate with other chemicals is effective for cleaning stone, bricks, concrete, and other construction materials, making it a valuable component in cleaning agents for these surfaces.
Used in Mineral Processing:
In the froth-flotation process, ZINC SILICOFLUORIDE acts as an active agent, aiding in the selection of valuable minerals by promoting their separation from unwanted materials.

Air & Water Reactions
Insoluble in water.
Reactivity Profile
ZINC SILICOFLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Health Hazard
Inhalation of dust irritates nose and throat; excessive inhalation may cause severe pulmonary inflammation. Ingestion causes nausea, cramps, vomiting, shock, convulsions, cyanosis, and other symptoms of fluoride poisoning. Contact with eyes or skin causes irritation; skin ulcers may develop.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride and silicon tetrafluoride are formed in fires.
Safety Profile
Poison by ingestion and
subcutaneous routes. When heated to
decomposition it emits toxic fumes of F-
and ZnO. See also ZINC COMPOUNDS.
Check Digit Verification of cas no
The CAS Registry Mumber 16871-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,7 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16871-71:
(7*1)+(6*6)+(5*8)+(4*7)+(3*1)+(2*7)+(1*1)=129
129 % 10 = 9
So 16871-71-9 is a valid CAS Registry Number.

Four novel linear trinuclear assemblies containing bridging triazole ligands. Crystal structure, magnetic, semiconducting and fluorescent properties

Four homotrinuclear linear coordination compounds with bridging ligand of (m-phenol)-1,2,4-triazole, [Mn3(L)6(H2O)6](ClO4)6 (1), [Ni3(L)6(H2O)6](BF4)6·4DMF (2), [Cd3(L)6(H2O)6](ClO4)6· 2H2O·2DMF·2EtOH (3), [Zn3(L)8(H2O)4](BF4)4(SiF6)·2EtOH·12H2O (4), have been synthesized and structurally determined. The structures consist of three metal ions in linear arrangements, linked to each other by two pairs of three N1, N2 bridging triazole ligands. The negative value of J suggests that antiferromagnetic interaction exists in 1. Green fluorescence of 2 and 4 with emissions at 518 nm for 2 and 524 for 4 is possibly assigned to LMCT. The energy gaps of the compounds 2 and 4 are 1.82 and 1.97 eV, respectively, which suggests that the two materials behave as semiconductors.
